Summary: Nanostructured graphene has been widely studied in recent years due to its tunable electronic properties for various fields. However, exposure of (3,1)-chiral graphene nanoribbons to oxidizing environments significantly oxidizes the ribbons and disrupts their electronic properties. Experiments show that even under gentle conditions, the ribbons are oxidized, providing insights into the reaction sites and defects caused by oxygen.

Summary: In this study, a tri-layer graphene nanomechanical resonant mass sensor was fabricated using a bottom-up process, demonstrating sub-attogram resolution at room temperature. Joule heating was found to be effective in cleaning the graphene membrane surface and improving the stability of the resonance frequency. The sensor was characterized by depositing Cr metal and showed sufficient mass resolution for weighing very small particles, such as large proteins and protein complexes, with potential applications in nanobiology and medicine.

Summary: The laser-induced formation of positive and negative ions on a nanostructured metal surface was observed below the plasma formation threshold. The dependence of the yield of positive and negative Au ions, charged clusters, and electrons on the laser radiation energy was investigated using a pulsed laser with a wavelength of 355 nm and a pulse duration of 0.37 ns. It was found that the ratio of positive and negative ion signals remained constant, while the ion signals followed a power function with an exponent of 9. The role of gold nanoparticles smaller than 5 nm in the formation of Au ions and charged clusters was discussed.

Summary: Carbocations can be utilized as laser-initiated footprinting reagents for proteins, with trifluomethoxy benzyl carbocation (TFB+) showing effectiveness in residue coverage of nucleophilic amino acids. The addition of TFB+ enhances peptide hydrophobicity, improving isomeric peptide separation by reversed-phase LC. TFB+ footprinting is sensitive to protein conformational changes, solvent accessibility, and has potential for membrane protein footprinting.

Summary: This study investigated the occurrence of traffic-derived magnetite particles in roadside soils on the Tibetan Plateau, revealing high levels of magnetite and associations with anthropogenic activities. The sources of magnetite particles were identified as mainly from traffic emissions, particularly wear particles, rather than natural sources. These findings highlight the impact of anthropogenic magnetite pollution from traffic emission on near-road residents.

Summary: Exposure to PM2.5 is a significant threat to human health globally. Understanding the distribution and processes of inhaled PM2.5 in the human body is crucial for establishing the causal links between PM2.5 pollution and diseases. However, research on the occurrence and fate of PM2.5 in humans is still limited. Therefore, further studies are needed to investigate the exposure pathways, distribution, and causal relationships between PM2.5 and diseases in the human body.

Summary: This study revealed the spatial distribution patterns of soil microplastics (MPs) in urban wetlands and their correlation with environmental and social factors. Through a large-scale wetland soil survey, the average abundance of MPs was found to be 379 n/kg with polypropylene, fiber or fragment, and black color being common composition, shape, and color, respectively. The results showed that MP abundance was significantly related to the distance from the urban economic center, soil heavy metal, and atmospheric particle concentrations, as well as the level of urbanization. Furthermore, the study found that urbanization level was the dominant factor driving MP pollution degree, with a total effect coefficient of 0.49. Overall, this work provides important environmental information for understanding and controlling MP pollution in urban ecosystems.

Summary: Ambient ultrafine particles in the human body have raised concerns about the risks of air particulate pollution. However, the ocular surface health risks associated with airborne particles are often overlooked. This study identified black carbon particles, a component of PM2.5, on the ocular surface using a mass spectrometry imaging method and found associations with ocular indices and dry eye disease. These findings highlight the potential ocular health risks and provide evidence for the neglected aspect of health impacts from PM2.5 exposure.

Summary: This study reports a matrix-free laser desorption/ionization mass spectrometry method for simultaneous analysis of elemental carbon (EC) and organic carbon (OC) species. By using this method, the adsorption process of per- and polyfluoroalkyl substances (PFASs) on carbon black (CB) was successfully monitored, and hydrophobic interaction was found to be the dominant adsorption mechanism. Furthermore, environmental substances such as humic acid and surfactants significantly affected the adsorption of PFASs on CB.

Summary: By using laser desorption ionization mass spectrometry (LDI-MS), the degradation pathways of black phosphorus (BP) were revealed at the molecular level without any chemical labeling. BP-based materials were found to generate characteristic peaks in LDI-MS, allowing the monitoring of the degradation processes. A new degradation pathway, nitrogen (N-2)-addition oxidation, was discovered using LDI-MS fingerprinting. These studies provide valuable insights into the chemical instability of BP and demonstrate a powerful platform for monitoring and characterizing material transformation.
